Hi,
If you want an opinion other than my own you might want to join my group
http://groups.yahoo.com/group/xenarthra_keepers/There are more owners on there. I made this since a lot of people don't want to venture into groups who are used to message boards but that's where all the action is.
There doesn't seem to be much difference in males and females personality wise. On the other hand most people do not keep them in their homes so some behaviors may be missed.
Males tend to want to mark more(little puddles of pee) while females tend to dribble more(drip drip drips of pee as they run around, involuntary), both are effected by being nervous or in a new area. Females dripping is effected by hormones too. With the monthly cycles you also have the monthly blood spotting to deal with.
Oh I think the males smell ickier, not stronger but their pee smells different from Puas and I like the smell of her pee better but that's just me.
